Magnet and Coil
Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of an ABS plastic molded cabinet, ABS plastic molded base, ABS milky white plastic molded operating surface with color silk-screened flip-up instruction board, delay circuit, stainless steel illuminated self-reset metal button, leakage protector, magnet, coil, LED light, start button, and operating handwheel. Press the button to start the magnet rotating, turn the handwheel to adjust the angle of the coil, and you will find that the brightness of the light bulb changes with the angle of the coil. Scientific Principle: What is the reason for this? In a closed circuit, when a conductor cuts magnetic lines of force in a magnetic field, an electric current is generated in the conductor; this is electromagnetic induction. When the 'U'-shaped magnet rotates, the magnetic lines of force in the magnetic field also rotate. Adjust the angle of the coil so that the magnetic lines of force form a certain angle with the plane of the coil; the coil cuts the magnetic lines of force, generating an induced current, and the light bulb lights up. When the magnetic lines of force are parallel to the plane of the coil, the coil does not cut the magnetic lines of force, so no induced current is generated, and the light bulb goes out. Electromagnetic induction is widely used in electrical engineering, electronic technology, electrification, and automation; for example, tape recorders and car tachometers are made using the principle of electromagnetic induction.
